Summary: We request a inhibit lock of DBus type UNIX_FD from systemd logind. It's wrapped into (and owned by) a QDBusUnixFileDescriptor object of automatic storage. The file descriptor will be closed in QDBusUnixFileDescriptor Dtor, and may be reused by some other facility (e.g. pulseaudio). If we want to store the lock longer than QDBusUnixFileDescriptor lifetime, we have to dup the file descriptor. If we don't dup, and close the original fd later in PresentationWidget::allowPowerManagement, bad things may happen. Besides that, what we get from systemd is really a file descriptor, not a "cookie". So I renamed the m_sleepInhibitCookie to m_sleepInhibitFd and changed initial state to -1 accordingly. BUG 393478 BUG 398720 Test Plan: - bugs don't occur any longer - inhibiting sleep during presentation mode still works Reviewers: aacid Reviewed By: aacid Subscribers: ngraham, anthonyfieroni, okular-devel Tags: #okular Differential Revision: https://phabricator.kde.org/D15574
